Longevity of Tooth Whitening by Hydrogen Peroxide using Cold Plasma

Objective: To evaluate the influence of acid erosion caused by the daily intake of lemon juice or apple cider vinegar, associated with immediate dental whitening, on bovine enamel. Materials and Methods: 30 bovine teeth were sectioned to obtain enamel blocks and were distributed into three groups (n = 10): G1- Tooth whitening with 35% hydrogen peroxide; G2- Tooth whitening with 35% hydrogen peroxide + lemon juice and G3 - Tooth whitening with 35% hydrogen peroxide + apple cider vinegar. Treatments were performed for 21 days, the varnish was removed and the analysis of loss of structure and surface roughness were performed by means of non-contact 3D Confocal Chromatic Profilometer. The roughness data obtained were analyzed by Kruskal-Wallis and Mann-Whitney non-parametric tests. Results: All groups exhibited greater roughness (Sa) on the side exposed to the treatments (G1 = 3.17b; G2 = 4.17b; G3 = 3.99b) compared to the unexposed side (G1 = 2.55a; G2 = 3.94a; G3 = 2.40a). There was a statistically significant difference among the groups evaluated, being G1 (3.17A) <G3 (3.99C) <G2 (4.17B). Conclusion: 35% hydrogen peroxide has the least erosive potential when compared to its association with vinegar and to lemon juice.

Introduction: Hyperglycemia in people with diabetes mellitus and its lack of control are associated with irreversible consequences. Glycation of proteins and enzymes, especially antioxidant enzymes in uncontrolled diabetes mellitus, affects these consequences. Consumption of bioactive compounds containing antioxidants and minerals as well as the use of adjunct therapies, such as cold atmospheric plasma therapy, can be effective in preventing and controlling the consequences of diabetes mellitus.Objective: In this research, we investigated whether cold plasma treatment of diabetic samples was effective in altering the activity of oxidative enzymes, some biochemical elements, and biochemical parameters.Methods: Thirty individuals with type 2 diabetes mellitus and 30 healthy individuals, as controls, participated in the study. The samples were exposed to cold argon plasma jet for 10 minutes (by a 10 kHz pulsed DC power supply with an amplitude up to 20.0 kV). The following contents of the serum samples of all participants were evaluated according to the instructions of the used kits before and after the cold argon plasma jet treatment: the activity of catalase, superoxide dismutase, and glutathione peroxidase enzymes; the concentration of glucose, hydrogen peroxide, and selenium binding protein 1 (as an indicator of blood selenium); and the concentration of copper, zinc, iron, and magnesium.Results: The activity of antioxidant enzymes and minerals significantly increased in diabetic samples treated with cold plasma (P value < 0.05). No significant changes were observed in the concentrations of glucose, hydrogen peroxide, or selenium binding protein 1 in diabetic samples treated with cold plasma.Conclusions: Using cold argon plasma jet as an adjunct method, which will reduce the glycation of enzymes and improve some minerals, can reduce the risk of diabetes complications in patients with diabetes mellitus.Keywords:Antioxidant enzymes, Cold plasma, Diabetes mellitus, Minerals.

Hoy en día existen varios métodos de aplicación del peróxido de carbamida e hidrógeno para su uso en el clareamiento dental, mediante esta investigación de la literatura se trata de determinar cuál es la mejor opción. Objetivo: Comparar mediante una revisión de literatura la eficacia del color y la sensibilidad dental producida por el peróxido de hidrógeno y el peróxido de carbamida. Método: Las bases de datos empleadas fueron PUBMED, Scopus y Web of Science. El método de búsqueda fue “TOOTH WHITENING AND HYDROGEN PEROXIDE AND CARBAMIDE PEROXIDE” aplicando los criterios de inclusión y exclusión se obtuvo 9 artículos para esta revisión de la literatura. Resultado: De acuerdo a los estudios analizados se encontró que todos los agentes aclaradores mejoran el aspecto del color de las estructuras dentales. En la mayoría de los estudios la sensibilidad dental, estaba presente; sin embargo, el peróxido de carbamida produce menos sensibilidad. Conclusión: El peróxido de hidrógeno como el peróxido de carbamida son efectivos para producir un cambio de color de los dientes. En los dientes más oscuros el tratamiento es más efectivo independientemente del agente aclarante utilizado. Por otro lado, la sensibilidad es menor cuando se aplica peróxido de carbamida.

Abstract Rapid innovation in vital bleaching has increased the popularity of tooth whitening among dental professionals and patients. A broad range of peroxide-based treatments are currently available including those that are professionally-administered (in-office), professionally-dispensed (custom-tray-based systems), and self-directed (over-the-counter). Recently, a novel, flexible polyethylene bleaching strip was introduced that delivers a hydrogen peroxide bleaching gel to the anterior dentition. This “trayless” system, available in professional-strength and over-the-counter versions, reportedly offers advantages with respect to overall peroxide dose, contact time, and ease-of-use compared to other delivery systems. This paper reviews the relevant published clinical research on whitening strips tested among a broad range of patients commonly encountered in contemporary dental practices.
